1533-生命防御的古老根基：人与细菌的抗病毒共性
from 聊聊Sci
人类细胞与细菌在抗病毒免疫机制上具有惊人的演化关联。这些研究揭示了诸如 cGAS-STING 和炎症小体等复杂的免疫通路并非人类所独有，而是起源于数十亿年前细菌对抗噬菌体的防御系统。通过跨界对比，科学家定义了病原体识别、信号放大及效应器功能等普适性原则。这些发现不仅打破了原有的学科界限，还建立了一个解释宿主与病毒交互的统一框架。目前，该领域正致力于通过分析这些古老的防御机制来开发新型疫苗和抗病毒疗法。此外，细菌中仍存在海量未知的免疫基因，为探索生命科学的底层逻辑提供了丰富资源。References:Kranzusch P J.

Deep Dream State
Neural Nets And Pretty Patterns
Deep Dream State is a full-cast dystopian sci-fi and desire horror audio drama by Neural Nets and Pretty Patterns. As the originating work of desire horror, it locates the uncanny inside wanting itself. While conventional horror positions you against a threat, desire horror implicates you in it. The horror emerges from recognition: the realization of why characters stay, and why surrender feels like relief. Since 2017, the show has used research in dream science, surveillance studies, behavioral economics, and advertising technology to examine systems of control through immersive sound design and full-cast performance.
